Enhancement for MIGO Tcode

Requirement 1: To Do Authorization validations while posting MIGO based on user code given to users.

1.    In MIGO at header level utilized existing field for entering user code given to post GR.

All User Codes will be given to each individual who are using MIGO for posting GR. All the user codes are maintained in custom table for validating in MIGO. If User enters valid user code then only they are able to post GR or else it will throw an error message. You are not authorized to post GR. All user codes will be confidential.

For this implemented logic in customer exit MBCF0002 (EXIT_SAPMM07M_001).

Requirement 2 : Add custom Tab in MIGO header for Adding Transporter details.

For this requirement implemented BADI MB_MIGO_BADI.

Before that append custom fields to MKPF table.

Create function module ZMIGO_BADI_PUT_HEADER for displaying custom field values when Created GR is in Display mode.

Source Code :

         ls_truckno     TYPE ztruckno,
         ls_driver      TYPE zdrivername,
         ls_courier     TYPE zlr_courier.

  IF zztransporter IS INITIAL.
    GET PARAMETER ID 'TRANS' FIELD ls_transporter.
    zztransporter = ls_transporter.
  ENDIF.

  IF zztruckno IS INITIAL .
    GET PARAMETER ID 'TRUCK'  FIELD  ls_truckno.
    zztruckno = ls_truckno.

ENDIF.

  IF zzdrivername IS INITIAL.
    GET PARAMETER ID 'DRIVER' FIELD ls_driver.
    zzdrivername = ls_driver.
  ENDIF.

  IF zzlr_courier IS INITIAL.
    GET PARAMETER ID 'COURIER' FIELD ls_courier.
    zzlr_courier = ls_courier.
  ENDIF.

       In method PBO Header add the custom tab screen created under function group.

1.       In method post document write logic to store values entered in custom fields in MIGO screen.

Function module Z_SET_DATA_MIGO_HEADER is used to get custom field values entered in MIGO.

Function Module ZEXPORT_MEMORY is used to place custom field values in Memory Id’s for using in later purpose .

This FM is of type Update FM because in MIGO (MKPF & MSEG or MATDOC table in HANA) Will get updated in Update task.

       In method STATUS_AND_HEADER implement logic to get custom field values updated in MKPF and place them in Memory to use in PBO Header Method in 

     ZMIGO_BADI_PUT_HEADER FM for displaying GR details in display mode along with custom values.

       Now most important thing is we need to write logic to update custom values in standard tables MKPF/ MATDOC.

For this created Implicit Enhancement in NSDM_MTDCSA_POST FM which is of Update Fm.

ENDENHANCEMENT.

In This FM get the custom values from Memory ID Stored in Badi in Post Document method in ZEXPORT_MEMORY FM and modify IT_MATDOC based on Material Doc number with Custom Values. Beacause IT_MATDOC is the table from which standard tables gets updated.
